Abstract

The invention discloses a method for optimizing the installation inclination angle of a photovoltaic panel based on representative horizontal plane radiation data, which can be applied to scientific researches and engineering applications in the fields related to renewable energy sources. In the invention, a method for determining the monthly optimum inclination angle, the season optimum inclination angle and the annual optimum inclination angle of a regional photovoltaic panel is put forward by using a solar radiation monthly mean model on an inclined plane based on representative daily solartotal radiation monthly mean value data on a horizontal plane, and the optimum inclination angle in different time periods is comprehensively analyzed. The method disclosed by the invention is applicable to various geographical and climatic conditions and has important significance in research for technologies related to photovoltaic power generation planning.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation planning, and specifically relates to a method for optimizing the installation inclination angle of photovoltaic panels based on representative horizontal plane radiation data, which can generate the best monthly inclination angle, the best seasonal inclination angle and the best annual inclination angle in an area. Background technique [0002] At present, with the improvement of people's awareness of saving energy and protecting the environment, new energy power generation has gradually become a research hotspot. Photovoltaic power generation occupies an important position in the power supply at home and abroad due to its cleanliness and richness of solar energy resources. When planning and designing a photovoltaic power generation system, since the solar radiation will change due to the change of the sun's position due to geographical latitude, seasons and time, the photovol...
